Answer:
Second option: y = 8x-3
Step-by-step explanation:
The equation tha satisfies the given values will be the required linear equation
So,
y = 8x + 45
For x=3 and y=21
21 = 8(3) +45
21 = 24+45
21≠69
As this equation is not satisfied by the values, it is not the correct option..
For y = 8x-3
x=3,y=21
21 = 8(3)-3
21 = 24-3
21=21
x=5, y=37
37 = 8(5)-3
37=40-3
37=37
x=7, y=53
53 = 8(7)-3
53 = 56-3
53 = 53
As the equation is true for all values of x and y. This is this correct option..
Subtract the difference in age from the total:
87 - 15 = 72
Divide by 2:
72 / 2 = 36
Sydney is 36 years old
Devaughn is 15 years older: 36 +15 = 51 years old
51 + 36 = 87
Answer B seems to have the increase we are looking for
Answer:
Step-by-step explanation:
Use SOH-CAH-TOA
Sin(25º) = x/10 (x being the height of the triangle)
x= Sin (25º) (10)
x = 4.23
Now for the base:
Cos (25º) = x/10
x = cos(25º)(10)
x = 9.06
Now solve for the area using 1/2bh
19.2 in^2
The answer you have selected is correct :)
